Datsyuk,hes got to be my favourite player of all time,how can you not like him?
Might not have been his usual self, but I remember watching his post-game interviews during the Sharks-Detroit series (don't remember which year), and he just didn't seem like a nice guy to the media. One guy asked him if he could talk about a certain play, and Datysuk responded with (paraphrasing here) "You have the video replays, look at them yourself".
Datsyuk is the ****ing man, I think anyone who hates on him just does so because he is so well liked and respected around the league by both fans and players. Stamkos is great too though, but I have to go with Datsyuk here.
